A nurse is collecting data from a client about range-of-motion for various joints. Which of the following should the nurse identify as an example of a ball and socket joint?
Ankle
Shoulder
Knee
Metacarpophalangeal
The Correct Answer is B
A. Ankle is incorrect. The ankle is a hinge joint, which allows for movement in one plane (up and down), not the multidirectional movement characteristic of a ball and socket joint.
B. Shoulder is correct. The shoulder joint is a ball and socket joint. This type of joint allows for movement in multiple directions, including flexion, extension, abduction, adduction, rotation, and circumduction.
C. Knee is incorrect. The knee is a hinge joint, allowing for flexion and extension but not the wide range of motion that a ball and socket joint offers.
D. Metacarpophalangeal is incorrect. The metacarpophalangeal joints (knuckles) are condyloid joints, which allow for movement in two planes but not the full rotational movement of a ball and socket joint.

Correct Answer is C
Explanation
A. Thrombocytopenia: Neither atenolol nor nitroglycerin is commonly associated with thrombocytopenia. This is not the primary concern when these two medications are used together.
B. Dry cough: A dry cough is a known side effect of ACE inhibitors (e.g., enalapril), but it is not commonly associated with atenolol or nitroglycerin.
C. Hypotension: Both atenolol (a beta-blocker) and nitroglycerin (a vasodilator) can lower blood pressure. When taken together, there is an increased risk of hypotension, especially when standing up quickly. The nurse should monitor the client for symptoms of low blood pressure such as dizziness, fainting, or lightheadedness.
D. Hyperglycemia: Atenolol may mask signs of hypoglycemia in clients with diabetes, but it does not directly cause hyperglycemia. Nitroglycerin is not typically associated with hyperglycemia either. Therefore, hyperglycemia is not a concern in this scenario.
Correct Answer is B
Explanation
A. Carrying the baby to the nursery is incorrect. Most facilities require that newborns be transported in a bassinet, not carried, to reduce the risk of accidental drops or abductions.
B. Having an identification band that matches the baby’s band is correct. Hospital security protocols require that the mother and baby wear matching identification bands to ensure the right baby is with the right parent and prevent infant abduction or misidentification.
C. Removing the security band to give to a family member is incorrect. The security band must remain on the mother at all times to verify identity when interacting with the baby. Removing it can compromise security.
D. Taking the baby to the lobby to visit family is incorrect. Many hospitals have strict policies requiring newborns to remain in designated areas for security and infection control reasons. Visitors should come to the mother’s room instead.
